Evidence of N120 shear corridors and associated tectonic structures in northeastern Tunisia after geological and geophysical data

The integration of 1:50 000 geological mapping, 2D seismic reflection profiles, and detailed new gravity data shows that northeastern Tunisia is affected by important strike-slip faults directed N120 and making shear corridors. At the both sides of these accidents, sedimentary series are affected by east–west to NW–SE and north–south to NE–SW faults, and NNE–SSW to NE–SW folds. N120 strike-slip faults initiated probably during the Late Cretaceous, and they have been activated during four distensive and compressive phases: Late Cretaceous, Late Eocene, Late Miocene, and Plio-Early Quaternary.
